Re: NAT on the Sitck

Yes, you can do that. It is not really "on the stick" because there is an outside (adsl) and one inside (VLAN1) interface.

Hope this helps, please rate post if it does!

Re: NAT on the Sitck

If you just need to access an inside webserver you don't need anything like that. Just configure:

ip nat inside source static tcp 192.168.1.9 80 interface Dialer0 800.

Note this assumes you are using PPPoA or PPPoE for the ADSL. Else, the interface name would be different.

Hope this helps, please rate post if it does!

Re: NAT on the Sitck

yes this for the nat beetween the interface. But me i want to see my webserver with the public address and use the nat rules.

ex:

i've already many rules bettween wan and lan :

ip nat inside source static tcp 192.168.1.9 80 interface Dialer0 80

ip nat inside source static tcp 192.168.1.9 443 interface Dialer0 90

ip nat inside source static tcp 192.168.1.9 21 interface Dialer0 98

and when i'am in the same lan of my web server ( in private ip), i wan't to access at the server with the @ipPublic:443 and use the corresponding NAT.

Did you have any solution ?

Re: NAT on the Sitck

I'm not you will succeed in doing that. AT some point the addresses will overlap between loopback and dialer. So you will have to access with private IP as long you are inside.

Re: NAT on the Sitck

yes but when i'am in the lan i can't test the natting between interface.

This fonction is actived by default in linksys wrt54G. How know the routing configuration in the linksys?

Re: NAT on the Sitck

On the other hand even if you can work out configuration for 'nat on a stick', you would be testing this one and not the NAT between ADSL and LAN that is what you care about.
